UDA : Unsupervised Data Augmentation

Unofficial PyTorch Implementation of Unsupervised Data Augmentation.

• Experiments on Text Dataset need to be done. Any Pull-Requests would be appreciated.
• Augmentation policies for SVHN, Imagenet using AutoAugment are not available publicly. We use policies from Fast AutoAugment.

Most of codes are from Fast AutoAugment.
